Mise en place partition

Support Debian
#1

Bonjour,

J’ai activé un RAID 1 depuis le bios sur 2 disques de 1TO.

Lorsque j’ai installé Debian Squeeze (net install), depuis le système graphique de l’installation, j’ai activé le RAID 1 sur ces 2 disques car il les voyait comme 2 disques de 1to.

Bref, après installation, ce disque en RAID1 n’est pas visible, comment puis-je procéder ?

Merci

Voilà le détail de quelques commandes :

Disk /dev/md0 doesn’t contain a valid partition table

[/code]

Je présume que le /dev/md0 doit donc être le disque en RAID1

Quelqu’un peut il m’aider svp ?
